SN74LS21N Ratings and Reviews

A***N

March 31 received the order. Everything is right and corresponds to the order. Unfortunately the parcel after admission to russia, about february 8, 19 came to me at the end of march. I had to even ask the seller to extend the protection period. The seller went to meet me. As a result, i'm happy. I recommend this store to order similar products. The seller fulfils its obligations. I think that when choosing the delivery service, you should choose the delivery with tracking if possible. Because for our state goods sometimes may not reach (just a gap), which i was confirmed by postal workers. But it does not depend on the seller. Without tracking is a game of russian roulette. Otherwise, i am happy and recommend this supplier. Sincerely anatoly.
